Answers

A process that could be represented by the letter A in the given diagram is fertilization. The correct option is D.

What is a reproductive cycle?

It goes through four stages: menstrual, regenerative, proliferative, and secretory. The cycle duration is the time it takes from the first day of one menstruation to the first day of the following menstruation; most usual cycles last 28 days, but it can range from 21 to 40 days.

The average cycle lasts 28 days; however, cycles can last anywhere from 21 to 35 days. The menstrual cycle is triggered by the rise and fall of chemicals in your body known as hormones.

Therefore, the correct option is D, fertilization.

suppose you add 20 ml of water and 20 ml of 0.50 g/l ca(oh)2 into a bottle. what is the concentration of ca(oh)2 in the bottle?

Answers

0.25g/L is the concentration of Ca(OH)2 in the bottle when 20 ml of water and 20 ml of 0.50 g/l Ca(OH)2 is added into a bottle.

What is Concentration?

Concentration in chemistry is the measure of the constituent divided by the volume of the mixture.

What is Ca(OH)?

Ca(OH)2 stands for Calcium hydroxide formed by the action of water on the calcium.it is used in forming a solution ,named limewater. it is also called as Slaked lime

Acc. to the given data:

c1=0.50g/l

v1=20ml=0.020L

c2=?

v2=20ml+20ml=40ml=0.040L

now we use the equation

c1v1=c2v2

rearranging the above equation

c2=c1*v1/v2

putting values

c2=0.50*0.020/0.040

c2=0.25g/l

Hence, 0.25g/L is the concentration of Ca(OH)2 in the bottle when 20 ml of water and 20 ml of 0.50 g/l Ca(OH)2 is added into a bottle.

an amino acid that forms a solution with a ph of 3.0 as it is dissolved in distilled water has a side chain with what functional group?

Answers

An amino acid that forms a solution with a ph of 3.0 as it is dissolved in distilled water has a side chain with a carboxyl group.

A carbonyl and hydroxyl group are joined by a carbon atom to form a carboxyl group. The hydroxyl group is made up of oxygen and hydrogen bound together, whereas the carbonyl group is a carbon double-bonded to oxygen (O=H) (OH). The carboxyl functional group, also known as the carboxyl group, is produced when the carbon atom is attached to both the hydroxyl and carbonyl functional groups.

This characteristic enables this functional group to bind to a variety of molecules that are present in typical goods. As a result, a molecule made up of a carbonyl and a hydroxyl group joined by a carbon atom is described as having a carboxyl group.

Answers

A drop of ink will spread faster as higher the temperature is. The higher the temperature, the more agitated the molecules will be, so they will move faster. So the mobility of the particles is related to their temperature.

So:

Particles in Flask C show the greatest mobility of the particles, this flask will have the highest temperature.

Particles in Flask A show the least mobility, this flask will have the lowest temperature.

Answers

The volume of carbon dioxide gas produced will be 23.3mL

SrCO (s) + 2HCl(aq) → SrCl₂(aq) + CO₂(g) + H₂O(l)

Here concentration of the strontium carbonate is in excess and the concentration of HCl is 25mL having molarity 0.1072 M

Number of moles of HCl= mass/ molar mass,

Molar mass of HCl= mass/ Number of moles

Molar mass of HCl= 36.5

Mass of HCl from balanced equation= 2×36.5=73

Molarity= Number of moles/ volume

According to stoichiometry the moles of HCl is 2 and that of  CO₂ is 1.

We know that,

PV =nRT

1.05× V= 1 ×0.0821× 298

V= 0.0821×298/ 1.05

= 23.3 mL

C6H12O6 + 6 O2(g) 6 CO2(g) + 6 H2O(g)
If 7.5 g of glucose react with 5.5 L of oxygen, which one is the limiting reagent?

Answers

C₆H₁₂O₆   +    6O₂    --->   6CO₂   +   6H₂O, If 7.5 g of glucose react with 5.5 L of oxygen,  the limiting reagent is glucose.

The balanced reaction is given as :

C₆H₁₂O₆   +    6O₂    --->   6CO₂   +   6H₂O

mass of glucose = 7.5 g

molar mass of glucose = 180 g/mol

number of moles =mass / molar mass

                            = 7.5 / 180

                            = 0.041 mol

volume of oxygen = 5.5 L

density of oxygen = 1.42 g/ml

mass = density × volume

mass = 1.42 × 5.5

mass = 7.81

moles = mass / molar mass

           = 7.81 / 32

           = 0.244 mol

mass of reactant from each product:

now, glucose ,  mass of CO₂ = 0.041 × 6 × 44 = 10.84 g

oxygen, mass of CO₂ = 0.244  × 6 × 44  = 64.41 g

Since glucose gives the smaller amount of product glucose is a limiting reagent.

Thus, C₆H₁₂O₆   +    6O₂    --->   6CO₂   +   6H₂O, If 7.5 g of glucose react with 5.5 L of oxygen,  the limiting reagent is glucose.

Explanation:

Fill in the table with the mass of each sample. Use the periodic table to find the molar mass of each compound. Then calculate moles and particles. Periodic TableThe two compounds have the same number of moles. Compare how the number of moles relates to the masses and number of particles for each compound.

Answers

1) First, let's calculate the molar mass of NaCl and CoCl₂:

Atomic mass of:

Na - 22.99 g/mol

Cl - 35.45 g/mol

Co - 58.93 g/mol

So for NaCl:

22.99 + 35.45 = 58.44 g/mol

Molar mass of NaCl = 58.44 g/mol

For CoCl₂:

58.93 + (2x35.45) = 129.83 g/mol

Molar mass of CoCl₂: 129.83 g/mol

2) Now let's find out the number of moles of each sample. For this, we use the following equation:

moles = mass / molar mass

NaCl:

mole = 116.8 / 58.44

mole = 1.999 moles of NaCl

CoCl₂:

mole = 259.7 / 129.83

mole = 2.000 moles of CoCl₂

3) To find the amount of particles, we use the Avogadro's constant. Avogadro's constant is a constant of proportion between the amount of matter and the number of entities that are linked to that amount. These entities can be atoms, molecules, ions, electrons, protons, neutrons.

In this case, we have the same number of moles, so we will have the same number of particles for both NaCl and CoCl₂.

Why do isotopes undergo radioactive decay?

Answers

Isotopes undergo radioactive decay because thermodynamics generally governs the situation. Every atom strives to have the greatest degree of stability. When the number of protons and neutrons in the atomic nucleus is out of balance, instability results in radioactive decay. In essence, the nucleus contains too much energy to keep all the nucleons together.

Radioactive decay a the spontaneous process through which an unstable atomic nucleus breaks into smaller, more stable fragments.

Three Types of Radioactive Decay:

Alpha Decay:

       When an alpha particle basically a helium nucleus with two protons and two neutrons is ejected, the parent's atomic number and mass number are reduced by two and four, respectively.

Beta Decay:

      A stream of electrons from the parent, known as beta particles, is released during beta decay, and a neutron in the nucleus is changed into a proton. The new nucleus has the same mass number, but an additional atomic number of one.

Gamma Decay:

        The atomic nucleus releases extra energy during gamma decay in the form of high-energy photons (electromagnetic radiation). The resultant nucleus takes on a more stable energy state while maintaining the same atomic number and mass number.

If 3.4 atm of a gas at 644.4 K is compressed to 11.6 atm at constant volume. What is the new pressure of the gas?

Answers

The temperature in the final pressure formation is 2201.13K and the change in the pressure is 8.2atm

It is given that the initial pressure of the gas P₁ is 3.4atm and the initial temperature is T₁ 644.4K the final pressure of the gas is 11.6 atm. To find the final temperature, According to Gay Lussac's Law,

P₁/T₁ = P₂/T₂

On substituting the values of P₁,T₁ and T₂ we get,

3.4/644.4 = 11.6/T₂

0.005276 = 11.6/T₂

T₂ = 11.6/0.005276

T₂ = 2201.13K

Therefore the final temperature T₂ is 2201.13K when the pressure is changed from 3.4 atm to 11.6 atm

Thus the pressure change is calculated by,

ΔP = P₂ - P₁

ΔP = 11.6 - 3.4

ΔP = 8.2 atm

The change in pressure is 8.2atm
